The DRIVER initiative for networking repositories

DRIVER motivation

Scholarly communication changes towards distributed provision of text, data and services

Repositories are thought as a saviour in this development building such a distributed system

An infrastructure supporting distributed repositories and services is needed

(and reactions)

(needs explanation)

Some observations on repositories

They represent a shift towards …open internet-exposure as opposed to closed database (‚graveyards‘)

content orientation as opposed to mere technical orientation (‚web-servers‘)

distributed systems centralized structures not immediateley required nowadays

„Everybody can be a publisher“Common description standards e.g. Dublin Core Metadata Initiative Many subject-specific standards

Common transfer protocols e.g. OAI-PMH, but also FTP, XML-RPC, WS, etc.

Searchability is possible!

Still: many results are lost to re-use/remixClosed: too sensible, weakly described, unimportant (???)

Missing service frameworks / infrastructures

Problems: Data and service interoperability

Solution: „Infrastructure“

Repositories can solve access problem

What infrastructures are: DRIVER terms

Not an infrastructureSingle repository

Single application for search and retrieval (e.g. BASE) Only local operation Backwards causation on repositories is missing

Maybe an infrastructureDistributed repository landscape as a whole As a capacity for emergent properties, e.g. quality and quantity

incentive for data population Nurturing development of service providers

Definitely an infrastructureMany service providers in one organisational and technical context (e.g. run-time environment)

Enabling re-use and remix of data and services

DRIVER Objectives

Organisational structure for repositoriese.g. the „Confederation“

Improving quality and standards in local rep.e.g. validation procedures

Building a distributed runtime systeme.g. service and data sharing

Target GroupsRepository Managers

Service Providers

Information System Executives

The DRIVER approach is incremental

Start with publication metadataExisting distributed system, somehow connected

Considerable homogeneity and formats: OAI-PMH

Extend geographical coverageFrom 5 countries, to 10, to 27, to ???

Extend towards other contentsFrom publication metadata to enhanced publications, i.e. representations of „texts + data“

Learn about subject specificityData bring in disciplinary requirements

DRIVER-II Services Enhanced publication management and functionality

Lessons learnt

Distributed data infrastructure requires links between organisational and technical concepts

Data specialists, computer scientists, service providers

Guidelines / content policies as a „glue“

In distributed data provision, quality and access measures are the most ‚expensive‘ tasks

Distributed service operation (not data provision) can be solved but asks novel questions (SLAs)

„Infrastructure“ is a very tough concept to get across and eventually forms a complex system

Simplification makes it weaker, e.g. re-use is restricted

Summary

DRIVER tackles the data infrastructure challenge from the text-repository side (mostly OAI-PMH)

DRIVER handshakes with primary & secondary data through „enhanced publications“

DRIVER isn‘t only a project but a forum for information specialists

‚Products‘ include: Studies, Infrastructure run-time-system in production, software, support …

DRIVER has adressed many problems for data and service interoperability and found solutions
